Hi Ed, Sorry for the delay in getting back to you. I'm not able to reproduce this problem. Could you try with # SYSTEMD_LOG_LEVEL=debug systemd-networkd-wait-online -i vhost0 ? Also, what is the output of $ networkctl status vhost0 when wait-online hangs? Cheers, Tom Tom. I am now hitting bug 97811 which needs to be fixed before I can test this. Thanks Ed (In reply to Ed Tomlinson from comment #2) > Tom. > > I am now hitting bug 97811 which needs to be fixed before I can test this. > > Thanks > Ed Thats: https://bugzilla.kernel.org/show_bug.cgi?id=97811 I am pretty sure this has been fixed in current systemd versions long ago. If this is reproducible on one of the two most current systemd versions (240, 241) please file a new bug on systemd github. |

This was working in previous versons. I am running an up to date arch install (218-2) with a 3.18-7 kernel. Something changed breaking a working setup. Ed Tomlinson
